T o all whom t may concern:

Be it known that l lALno HAnALsoN, a

citizenof the United tates, residing Aat Las Animas, in the county ofBent, State of Colorado, have invented certain new and usefulImprovements in Door-Stops; and l do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

rlhis invention relates to door stops and it has for its object toprovide an article that will be extremely cheap of manufacure, that maybe readily and properly applied without the attention of a skilledmechanic and which not only will effectively hold the door againstmovement when such action is desired, but may be easily and quicklymoved to inoperative position when not to be used.

In the drawings:

Figure 1 is a view showing the lower portion of the door with thepresent stop in place thereon and in its active position.

Fig. 2 is an enlarged elevation showing the crank mechanism by which thepresser foot is raised and lowered, such mechanism being illustrated inthe position with the presser foot raised.

Fig. 3 is a vertical section on line 3-3 of Fig. 1, a portion of the rodof the foot being omitted to permit of showing on a larger scale.

Referring now to the drawings there is shown at 5 a portion of the doorequipped with the present invention. The present stop comprises a casingwhich is opened at its i'ear side and its lower end and which casing isillustrated at 6. From the longitudinal edges of the rear opening of thecasing, there extend the lateral flanges 7 thatV are perforated toreceive screws or bolts 8, through the medium of which the casing issecured upon the face of the door at its outer lower corner and with itsopen' end directed downwardly.

lVithin the casing is slidably disposed a rectangular socket member 8which is h ollow and has its lower end open to receive a rubber plug 9,this socket member and plug constituting the foot of the door stop. Thecasing 6 is cross sectionally rectangular and while permitting thesocket member to slide in it, prevents rotation of the latter,

the advantage of. which will be presentlyv explained. i

VThe upper end of the socket member 8 is centrally perforated to receivea rod 10 having a head 11 within the socket .mem-

ber to prevent withdrawal Vof the rod from it, this rod extendingupwardly and through a corresponding perforation'in the top of ec f thecasing 6. Within the casing, surrounding the rod 10 and bearing with itsends respectively against the socket member and the top of the casing,is a helical spring 12 that tends to hold the foot withthe rubber plug10 projected beyond the lower edge of the door and in intimateycontactlv with the surface of the floor 13, thus to hold the dooragainst swinging.

lnlorder to raise the foot to inoperative position and hold it thus,there is mounted upon the same face of the door, a'carrier yplate 18having securing means such as screws 14 Y at its margin and having alsoa central screw 15 which is passed through it and into the material ofthe door. forms a pivot of a hand lever or crank 16, the pivotal bearingof which is formed in a finger 17 that is directed laterally from theside of the crank arm at a point between its ends and near to one end.To the nearer end of the crank arm 16 is pivoted the upper end'of therod 10 while at the other end of theA arm 16 is the crank handle 17.When the foot is inoperative position, the crank stands at one side ofits pivot 15 and when it is desired to raise the stop and hold itraised, the crank is operated to carry its lower end upwardly and overits pivot, with the crank arm at the opposite side of the pivot andinverted from its original position, at which time the crank handle willlie against the rod 10 and hold the foot against downward movement underthe influence of its helical spring. The spring thus serves to hold thefoot yieldably in both its active and its inactive positions By reasonof the socket member being rectangular and corresponding in crosssectionalshape to the casing, rotation of the foot is prevented so thatstrains that would disrupt the connections between the two parts' Thisscrew 15V are prevented from passing to them while the rubberV plug maydrag only 'laterally to the swinging of the door.
